Nice we can party like it’s 1999!
It took 20 years to come full circle. Crazy. I assume it’s because early GPUs didn’t have the storage or processing power to accept the full scene geometry and culling was left up to the CPU.

Maybe hardware wasn't really ready for it but it is now?
Did the vector unit operate on work groups and have local memory?
Work probably differently but have the same function and it looks like it is a relief for developer.
And the other answer shows they are happy to go back to square one. A more exact term would be Mesh shading is an evolution of PS2 VU...
They would probably have been more happy to improve from the PS2 VU idea...

Based on the prior tweets I think GS meant Geometry Shader though when used while discussing PS2 I can see your interpretation.
AMD has an ES stage when GS is used.
SIGGRAPH 2019: Applications of Mesh Shading with Dx12
This has the 2nd part of the talk as well, implementation of DX12 tessellation using mesh shaders.

Talk about mesh shaders
NetEase developer Thunder Fire Games, developers of Justice (MMO) have added Mesh Shaders to their rendering pipeline..allowing for over 1.8 billion triangles running at over 60fps @ 4K on an RTX 3060Ti.
Demo video:

Justice supports 8K DLSS, as well as RTXGI global illumination.

It's a nice little demo for sure.
I think we're going to see some amazing looking stuff coming up in the near-ish future, once developers have all these advanced features ready in engine.. and development pipelines are well integrated.
They speak about high resolution textures being a must. To really show off the models at this high of a geometric density, you need high frequency textures to go along with it.. so you can see how Sampler Feedback Streaming plays into enabling this on a larger scale. They don't speak about supporting SF yet, at least not in the article, so I'd assume that is another thing they will be updating to there renderer in the future.
